New paper explains how natural ocean oscillations control clouds and temperature thousands of miles away

A new paper published in Climate Dynamics finds a mechanism by which the natural North Atlantic Oscillation [NAO] controls atmospheric waves that affect cloud formation, which in turn controls surface temperatures and crop yields in far-away NE China [over 8,000 miles from the Atlantic].

Climate alarmists simplistically claim warming increases water vapor in the atmosphere and clouds, and erroneously claim that clouds have a positive feedback effect to cause more warming. However, this new paper finds stronger cold surges increase cloud formation, and that those clouds have a cooling and moderating effect on temperatures: 

"stronger cold surges can accordingly increase cloud amount, resulting in an a decrease in daily maximum temperature and an increase in daily minimum temperature, thereby leading to a decrease in the daily temperature range." [and vice-versa as shown below]

The NAO, in turn, has been linked to solar activity, as well as Rossby waves

The last portion of the abstract is easier to understand if broken into the 2 components:

1. Weaker cold surges can accordingly reduce  cloud amount, resulting in an increase in daily maximum temperature and a decrease in daily minimum temperature, thereby leading to an increase in diurnal temperature range.

2. (stronger) cold surges can accordingly  (increase) cloud amount, resulting in an (a decrease) in daily maximum temperature and a (an increase) in daily minimum temperature, thereby leading to (a decrease) in diurnal temperature range.

Influence of springtime North Atlantic Oscillation on crops yields in Northeast China

Mengzi Zhou et al

Forecasting grain production is of strategic importance in considerations of climate change and growing population. Here we show that the springtime North Atlantic Oscillation (NAO) is significantly correlated to the year-to-year increment of maize and rice yield in Northeast China (NEC). The physical mechanism for this relationship was investigated. Springtime NAO can induce sea surface temperature anomalies (SSTAs) in the North Atlantic, which display a tripole pattern and are similar to the empirical mode pattern in spring. The spring Atlantic SSTA pattern that could persists to summer, can trigger a high-level tropospheric Rossby wave response in the Eurasia continent, resulting in atmospheric circulation anomalies over the Siberia-Mongolia region, which is unfavorable (favorable) for cold surges that affect NEC. Weaker (stronger) cold surges can accordingly reduce (increase) cloud amount, resulting in an increase (a decrease) in daily maximum temperature and a decrease (an increase) in daily minimum temperature, thereby leading to an increase (a decrease) in diurnal temperature range. And summer-mean daily minimum temperature and diurnal temperature range are most significantly related to the NEC crop yields.
